If the engine dies when the blades engage, it could be the result of a damaged safety switch. The first step in assessing the safety switch is to make sure it is plugged in securely. The switch is located underneath the seat, and you may have to remove the seat to reach it.
This is most likely a safety switch issue. Usually the seat safety switch will cause this problem. The mower dies because it thinks nobody is sitting in the seat, and shuts off for safety reasons.
Check that all the safety switches are working correctly, it is possible the seat switch is bad or loose plug/ bad wire. Also if battery weak or charging system weak/faulty the clutch will stall out engine, charge battery up with charger and try.
A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
Clogged or Dirty Air Filters
It is one of the most common problems that cause lawnmowers to sputter. The mowers take the air from the surrounding through air filters and mix it with fuel inside the engine. So, if the air filter is clogged or dirty, it will affect the flow of air into the carburetor.
Over time, a spark plug will wear out. Eventually, the spark will no longer be powerful enough to fully ignite the air and fuel. You are likely to notice power loss including bogging down when cutting grass because of a worn spark plug. Removing and replacing a spark plug is easy.
Belt-the number one cause for your blades not to engage is that your belt is either stretched or loose causing it to slip or fall off completely. Belt could have snapped also. When you are trying to process too much grass/leaves they could pack up under your deck and push off your belt.
The most common reason for a surging lawn mower engine is a blockage in the fuel supply, but there are other possibilities: Bad gas. Bad spark plug. Dirty/faulty carburetor.
